Favorite anime song

[Alfieri]

I don't mean openings or endings. I'm talking about your favorite song in an anime's soundtrack that plays during the episodes.

My 2 personal favorites are:
Yusuke Power Up Theme: https://www.youtube.com/watch?v=rS0uZUOkHAw
When I first heard this song playing during Yusuke's counterattack on Sensui, I was extremely pumped and rooting for Yusuke the whole way through. It's such an awesome song and really fits the whole demon power up mood.

Vizard Theme: https://www.youtube.com/watch?v=bVnQO9XaKB0
I recently began watching Bleach and when I first met the Vizards, I wasn't too crazy about them. However Shinji's theme that plays when fighting Grimmjow is really cool. I love the rhythm and it sounds so fancy for such a weird funny guy lol.

Here's an old AMV of my favorite insert song from Digimon Savers.

"Believer"

It's very intense.

Out of all the Digimon songs, i would say WE ARE XROS HEART X7 https://www.youtube.com/watch?v=tNzrqFs5U_E
Butterfly is really close to my favorite too, and so are most other Digimon songs actually.

I also like the opening of Code Geass https://www.youtube.com/watch?v=oXwrFZmIuAY , if it counts

It's called anime soundtracks.

As an avid soundtrack listener, there's a lot that I like, but some notable ones:

Sis Puella Magica and Credens Justitiam from Puella Magi Madoka Magica.
The Palm of a Tiny Hand from CLANNAD (it's in the soundtrack collection, so it counts)

Will edit with links later.

The Reluctant Heroes from SnK is amazing imo, and also the Attack on Titan OST (idk if it has an official name cause that's what I see everywhere) is amazing too.

Death the Kid's theme from Soul Eater is always really awesome! I also really like all of the Magi openings.
